JOSEPH FITTON, OF BUFFALO, NEW YORK.

HYDROCAFIBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 788,764, dated May2,1905.

Application filed June 2l, 1904. Serial No. 213.529.

To (if/ZZ whom, 'fit l1/Mtg adn/cern:

Be it known that I, J osnPI-I FIT'roN, of the United States Navy, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Hydrocarbon-Burners; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. p

My invention relates to hydrocarbon-burners, and has for its object athorough atomizing of the oil and the diffusion of steam or air with theoil to produce the best results attainable in the combustion of theliquid fuel; and the invention consists in certain improvements inconstruction over my previous invention for which Letters Patent No. 733,57 9, dated July 14, 1903, have been granted to me, and Which will befully disclos'ed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical longitudinal section of my improvedburner, and Fig. 2 a transverse section on line A B. Fig. 3 is atransverse section on line O D, and Fig. 4 is an enlarged transversesection of the guard 26 at the line E F.

Reference being had to the drawings and the designating charactersthereon, 1 indi- Cates the body or casing, provided with a pipe 2 forsupplying' steam or air to the annular chamber 3, surrounding theremovable oilpipe 4, from which the air or steam is discharged throughpassages 5 in the spider Gat the inner end of the body or casing 1. Atthe outer end of the casing 1 is a stufiing-box 7, having an adjustablegland 8, externally screw-threaded to engage the internal screwthread inthe end of the body 1 for the purpose of making a steam or air tightslip-joint between the casing 1 and the oil-pipe 4. '.lhe oil-pipe 4 atits outer end is provided with a lug 9, by which it is actuated throughthe medium of the rod 10, threaded at its end to the lug 11 on the outerend of the casit 1; The rod 10 is provided with collars or Jamnuts 12embracing the lug 9, as also with a hand-wheel13 at itsouter end for thepurpose of adj Listing and regulating the width of the annularvalve-opening which is formed by the separation of the seat-faces 27 and14 and through which the steam or air is admitted into contact with theoil emanating from the opening' 15. (Shown at the inner end of .the pipe4.)

The end of the pipe 4toward the end of the' burner where the oil isignited is provided with a needle-valve 17, operated by the stern 18through the means of the hand-wheel 21. The valve end of the stem18slides in a guide 30, formed on the inner end of the nozzle 23, for thepurpose of holding the valve 17 centrally in position relatively to thepassage 15 and has grooves 16 formed into same to admit the passage ofthe oil, the supply of which to the furnace is regulated by the valve17. The stem 18 is provided with a threaded section 90 and astung-hox19, with its gland 22, for effecting' an oil-tight slip-joint betweenthe stem 18 and the pipe 4.

The valve-seat of the valve 17 forms thereceiving side of4 the nozzle23, which is preferably connected to the pipe 4 by screwthreads, asshown, and in addition to the conical valve-seat for the valve 17 it isprovided with a contracted parallel passage 15 anda conical orflaring-walled discharge-mouth 24, in which is a ball 25, securedagainst displacement by a guard 26 on the upper side of the ball, asshown, this guard in cross-section at the line E F being' preferably ofthe form shown by the enlarged view Fig. 4 for the purpose of preventingthe oil adhering thereto and discharging into a stream outside of theburner. The guard E26 is held in place by means of the set-screw 23bearing on its head, as shown, for the purpose of its convenient removalor renewal. The nozzle 23 is provided with a conical seat 97, which isparallel to the angle of the seat 14 on the body 1 and forms avalve-opening for regulating the supply of air or steam by means of thehand-wheel 13. The pipe 4 is provided with a spider-bearing around itsperiphery at its inner end, as shown by the transverse section, Fig. 3,:for the purpose of keeping the pipe 4 in alinement, so that the annularvalve-opening 14 will be maintained at a uniform width IOO under thedistorting iniiuence of the furnaceheat.

The oil is supplied to the burner through the inlet Q9 of the pipe 4under pressure by means of a suitable pump` (not sho\vn,) and by itsdischarge through the aperture 15 it causes the ball Q5 to revolverapidly, and the ball is drawn toward its seat by the outflowing streamof oil', its intensity of pressure in that direction being' proportionalto the velocity of the oil due to the pressure under which it is forcedthrough the aperture 15, so that the thickness of the annular sheet ofoil varies according to the intensity of the force With which the balltends toward its seat.

By the form or design of construction herein shown the oil is firstintroduced into the pipe 4, which is surrounded with the jacket orchamber 3, and in the case of using' steam its iiuidity is increasedfrom the heat imparted to it by the steam and flows more readily throughthe valved aperture, by means of which its quantity from theconduit-pipes into the burner is more finely regulated than in the caseof my previous invention herein mentioned, especially with thc heavieror thicker oils. I

The form of construction herein shown also enables the oil beingintroduced through the valved nozzle-opening 15 under the delivery orinitial pressure of the supply, and thereby affords a higher exitvelocity in its discharge through said opening 15 than is the case in myprevious invention mentioned especially when the amount of oil being fedto the burner is less than the maximum discharge capacity of the burner,and causes the ball to be drawn toward its seat with greater force, andconsequently producing a thinner sheet of oil to be projected againstthe sheet of steam or air with higher velocity than is the casein mysaid previous invention, and thereby more thoroughly atomizes the oiland effects its combustion with i less expenditure of steam or air thanthat required by my said previous invention.

Having thus fully described my invention, what I claim is# 1. Ahydrocarbon-burner consisting of an oil-delivery pipe 4, provided Withan oil-inlet connection 29, and a valve-stem 18, and a stufHng-box 19for said stem, and spider-bearing 6, and also provided withadischarge-nozzle 23, said nozzle having a valve-stem guide 30, valvedpassage 15, valve-seat 27, and a diverging mouth 24, said mouthcontaining a ball 25, and guard 26, said guard being held in place witha screw 28; in combination with a casing 1, forming the Walls of achamber 3 having outlet-passages 5 through the spiderbearing, saidcasing formed With a valve-seat 14 and a stuiiing-box 7, for theoil-pipe and provided with an inlet-opening 2, and an adjusting-stem10;all substantially as and for the purposes set forth.

2. A hydrocarbon-burner consisting of an oil-delivery pipe 4, providedwith an oil-inlet connection 29, and a valve-stem 18, and a stuffing-box19 for said stem, and spider-bearing 6, and also provided withadischarge-nozzle 23, said nozzle having a valve-stem guide 30, valvedpassa-ge 15, valve-seat 27 and a diverging mouth 24, said mouthcontaining a ball 25, and guard 26; in combination with a casing 1,forming the Walls of a chamber 3 having outlet-passages 5 through thespiderbea ring, said casing formed with a valve-seat 14 and astuffing-box 7 for the oil-pipe and provided with an inlet-opening Q andan adjusting-stem 10; all substantially as and for the purposes setforth.

In testimony' whereof I aiix my signature hereto in the presence of twoWitnesses.

JOSEPH FITTON.
